Gnaphalium uliginosum, the marsh cudweed,[2] is an annual plant found on damp, disturbed ground and tracks. It is very widespread across much of Europe, Asia, and North America.[3][4][5] It is very common on damp, arable grasslands, paths, and on acid soils.

Description

[edit]

It is a very woolly annual, growing 4–20 cm tall.[6]

The leaves are wooly on both sides. They are 1 to 5 cm long, narrow oblong shaped.[6]

The flower heads are 3 to 4 mm long. They are arranged in clusters of 3 to 10, surrounded by long leaves. The flower head bracts are wooly, and pale below, with dark chaffy hairless tips. The florets are brownish yellow. The stigmas are pale.[6]

It flowers from July until September.[6]
